DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As shown in FIGS. 1 and 2, the present invention provides a buildingblock unit and an assembling structure of the building block unit, andthe building block unit includes a main body 1.

The main body 1 is a polyhedron, and preferably, the main body 1 is ahollow polyhedron. The main body 1 has at least one assembling hole 2and at least one assembling portion 3 which are respectively disposed ontwo different faces of the main body 1. More specifically, the main body1 has correspondingly a first face 11 and a second face 12 and aplurality of lateral faces 13 connected to the first face 11 and thesecond face 12. The assembling hole 2 and the assembling portion 3 arerespectively disposed on each two of the first face 11, the second face12 and the lateral faces 13. Preferably, in this embodiment, the mainbody 1 is a hexahedron, and each face of the hexahedron isquadrilateral, but in other possible embodiments, the faces of thepolyhedron could be in other shapes, such as triangular, circular, orthe like. The main body could even be a cone. Preferably, the main body1 can be made of paper (but not limited thereto). Consequently, thepresent invention is not only practical but also environment-friendly,and of course, the main body could also be made of other materials, suchas plastic.

The assembling portion 3 has a cutting line 31 which is non-straight andhas two corresponding ends at different positions. More specifically,the cutting line 31 is substantially an arc line, and a head portion 32is defined by the cutting line 31 to be substantially arc-shaped. A neckportion 33 is formed at the connecting section between the head portion32 and the main body 1 to enable the head portion 32 to be swingablerelative to the main body 1. Preferably, the largest width of the headportion 32 is larger than the width of the neck portion 33, and a vergeof the head portion 32 of the assembling portion 3 is substantiallyserrated (as shown in FIG. 1A).

The assembling hole 2 has an engaging portion, and at least the width ofthe engaging portion is smaller than that of the head portion 32, so thehead portion 32 can be stuckable in the assembling hole 2 and won't falloff easily. In this embodiment, the assembling hole 2 is a circular holewhose largest width is between the largest width of the head portion 32and the width of the neck portion 31, and the hole edge of theassembling hole 2 has the same structure as the verge of the headportion 32 and has substantially serrated shape (not shown).

In this embodiment, the main body 1 is formed with two assembling holes2 and two assembling portions 3, 3′, and each of the two assemblingholes 2 and each of the two assembling portions 3, 3′ are respectivelydisposed on each two of the first face 11, the second face 12 and thelateral faces 13. Preferably, in this embodiment, the assembling holes 2are disposed on the first face 11 of the main body 1, and the assemblingportions 3, 3′ are disposed on the second face 12 of the main body 1;the assembling holes 2 and the assembling portions 3, 3′ are disposed incorresponding positions and distributed in equal density. Preferably,each head portions 32, 32′ of each assembling portion 3, 3′ is swingablerelative to the main body 1 around a corresponding axis, and the axes ofthe head portions 32, 32′ of the two assembling portions 3, 3′ extend indifferent directions. More specifically, when the head portions 32, 32′of the assembling portions 3, 3′ are swung relative to the main body 1along the neck portions 33, 33′, the head portions 32, 32′ of the twoassembling portions 3, 3′ are swung in different directions. In otherpossible embodiments, the main body can be formed with one or more thantwo assembling hole(s) and assembling portion(s).

As shown in FIG. 3, the present invention further provides a buildingblock assembling structure, including a plurality of building blockunits mentioned above. This embodiment uses two building block units toillustrate (but not limited thereto), and it is possible to include morethan two building block units in other embodiments. Each building blockunit includes a main body 1, 1′, wherein the width of the engagingportion of the assembling hole 2′ of the main body 1′ is smaller thanthe largest width of each head portion 32, 32′ of another main body 1;therefore, when the head portions 32, 32′ of the main body 1 are swungrelative to the main body 1, the head portions 32, 32′ of the main body1 can be disposed through and stuck at the engaging portion of theassembling hole 2 of the main body 1′. Preferably, the largest width ofthe assembling hole 2′ of the main body 1′ is between the largest widthof each head portion 32, 32′ of another main body 1 and the width ofeach neck portion 33, 33′, so when the head portions 32, 32′ of the mainbody 1 are swung relative to the main body 1, they can be disposedthrough and stuck in the assembling hole 2′ of another main body 1′ andwon't fall off easily. More specifically, because the main bodies 1, 1′of each building block unit is a hollow polyhedron, wherein each headportion 32, 32′ of the main body 1 of a building block unit can be swungoutward relative to the main body 1, stuck in one of the assemblingholes 2′ of the main body 1′ of another building block unit and disposedin the main body 1′.

In practice, users can push the head portions 32, 32′ outward and makethem get stuck in the engaging holes 2′ of another main body 1′ throughthe assembling holes 2 of the main body 1. Furthermore, the verges ofthe head portions 32, 32′ are serrated and the hole edges of theassembling holes 2′ are also serrated; therefore, when the head portions32, 32′ are stuck in the engaging holes 2′, part of the verges of thehead portions 32, 32′ will engage with the hole edges of the assemblingholes 2′ to make the engagement of the head portions 32, 32′ and theassembling holes 2 more stable. More specifically, the assemblingportions 3, 3′ of the main body 1 are distributed in equal density, andthe assembling holes 2′ of another main body 1′ are distributed in equaldensity; hence, the main bodies 1, 1′ can be corresponding to each otherand piled up, and the main bodies 1, 1′ can be fixed via the engagementof the assembling portions 3, 3′ and the assembling holes 2′.

Besides, since the directions of the head portions 32, 32′ swung aredifferent, the directions of the engaging forces between the headportions 32, 32′ of the main body 1 of a building block unit and theassembling holes 2′ of another building block unit are different.Therefore, when each head portion 32, 32′ of the main body 1 of abuilding block unit is stuck in one of the assembling holes 2′ ofanother building block unit, the two building block units won't fall offfrom each other easily.

Given the above, the present invention provides the building block unitand the assembling structure of the building block unit. Through theassembling portion and the assembling hole of each of the building blockunit, each two building block units can be assembled or combined to formthe building block assembling structure, and it is easy for users toassemble and pile up the building block units. In addition, the buildingblock unit is hollow, and the assembling portion is selectivelyswingable; thus, when users finish constructing the shape or structurethey want, they can fold the assembling portions inward into thebuilding block unit. Compared with the prior arts, the building blockassembling structure piled up with the building block unit of thepresent invention looks good in appearance because there are nounnecessary studs.
